Configure Virtual Servers
Run the libvirt qemu setup script:
$ bash setup_all_in_one.sh
Simplex Virtual Environment
Controller-0 Host Installation
Installing controller-0 involves initializing a host with software and then applying a configuration from the command line. The configured host becomes Controller-0.
Procedure:
- Using an ISO image of StarlingX, initialize the controller host via Libvirt/QEMU.
- Configure the controller using the config_controller script.
Initializing Controller-0
This section describes how to initialize StarlingX in host Controller-0. Except where noted, all the commands must be executed from a console of the Workstation. Make sure Virtual Machine Manager is open.
From the KVM/VirtManager window, power on the host to be configured as Controller-0 and show the virtual machine console and details:
- When the installer is loaded and the installer welcome screen appears in the Controller-0 host, select the type of installation "All-in-one Controller Configuration".
- Select the "Graphical Console" as the console to use during installation.
- Select "Standard Security Boot Profile" as the Security Profile.
- Monitor the initialization until it is complete. When initialization is complete, a reboot is initiated on the Controller-0 host, briefly displays a GNU GRUB screen, and then boots automatically into the StarlingX image.
Log into Controller-0 as user wrsroot, with password wrsroot. The first time you log in as wrsroot, you are required to change your password. Enter the current password (wrsroot):
Changing password for wrsroot. (current) UNIX Password:
Enter a new password for the wrsroot account:
New password:
Enter the new password again to confirm it:
Retype new password:
Controller-0 is initialized with StarlingX, and is ready for configuration.
Configuring Controller-0
This section describes how to perform the Controller-0 configuration interactively. Except where noted, all the commands must be executed from the console of the active controller (here assumed to be controller-0.
When run interactively, the config_controller script presents a series of prompts for initial configuration of StarlingX. The script is used to configure the first controller in the StarlingX cluster as controller-0. The prompts are grouped by configuration area. To start the script interactively, use the following command with no parameters:
controller-0:~$ sudo config_controller System Configuration ================ Enter ! at any prompt to abort... ...
Select [y] for System Date and Time:
System date and time: ----------------------------- Is the current date and time correct? [y/N]: y
Accept all the default values immediately after ‘system date and time’.

Controller-0 Host Provision
On Controller-0, acquire Keystone administrative privileges:
controller-0:~$ source /etc/nova/openrc
On Controller-0, create a newshell script file, copy and paste the content below and run:
The host is rebooted. During the reboot, the command line is unavailable, and any ssh connections are dropped. To monitor the progress of the reboot, use the controller-0 console.
Verifying the Controller-0 Configuration
On Controller-0, acquire Keystone administrative privileges:
controller-0:~$ source /etc/nova/openrc
Verify that the Titanium Cloud controller services are running:
[wrsroot@controller-0 ~(keystone_admin)]$ nova service-list +--------------------------------------+------------------+--------------+----------+---------+-------+ ... | Id | Binary | Host | Zone | Status | State | ... +--------------------------------------+------------------+--------------+----------+---------+-------+ ... | d7cdfaf0-9394-4053-b752-d609c837b729 | nova-conductor | controller-0 | internal | enabled | up | ... | 692c2659-7188-42ec-9ad1-c88ac3020dc6 | nova-scheduler | controller-0 | internal | enabled | up | ... | 5c7c9aad-696f-4dd1-a497-464bdd525e0c | nova-consoleauth | controller-0 | internal | enabled | up | ... +--------------------------------------+------------------+--------------+----------+---------+-------+ ...
If one of the listed services is down please reenable
#!/usr/bin/env bash
source /etc/nova/openrc
ALL_DISABLED_SERVICES=`nova service-list | grep disabled | awk -F "|" '{print $2}'`
for service in $ALL_DISABLED_SERVICES; do
nova service-force-down --unset ${service}
nova service-enable ${service}
done
Verify that controller-0 is unlocked, enabled, and available:
[wrsroot@controller-0 ~(keystone_admin)]$ system host-list +----+--------------+-------------+----------------+-------------+--------------+ | id | hostname | personality | administrative | operational | availability | +----+--------------+-------------+----------------+-------------+--------------+ | 1 | controller-0 | controller | unlocked | enabled | available | +----+--------------+-------------+----------------+-------------+--------------+
